Chapter 288 Are There Mistakes In The Classic Genre?
Song He walked to the podium and watched the paper correction.
Xiong Maoxun and Ye Li didn't leave either, watching silently.
Yu Anbang's red pen quickly crossed over, and the small questions in front were all marked, which was pleasing to the eye.
When it came to the first big question, the tip of the red pen hesitated, crossed out 80% of the steps, and only gave two points for the beginning.
Then the second big question was all correct, and the third big question was blank.
"72 points." Yu Anbang said regretfully, "Good."
"Teacher, I should have got the first question right." Song He argued calmly.
"The correct answer is 87.667. The Tolkien-style advanced solution you used for your first route was originally correct, but you crossed it out!" Yu Anbang said helplessly, "The second route you kept has a result of 87.687. Although the result It’s so close that it seems like a small error, but it’s wrong. Did you create this route yourself?”
"No." Song He shook his head, "The second route is the solution of the You Deyi Sect."
Yu Anbang was stunned and didn't react for a while.
Xiong Maoxun and Ye Li next to them were about to leave, but they stopped in surprise after hearing this.
"It's very simple to use the traditional Tolkien solution. You can find the result of 87.667 in one go." Song He said seriously, "But I tried to solve it using the theory of the Youdeyi School and found that the value is 87.687."
"Have you learned the Youdeyi sect?" Yu Anbang asked with a ghostly expression.
"I learned a small part, about one-fifth." Song He asked, "Do you want me to explain the idea of this question? I believe my answer is correct."
"Speak!" Yu Anbang nodded dubiously.
"At first, when I used two methods to calculate two similar results mentally, I thought it was a calculation error. But after I repeated the mental calculation two or three times, the values remained fixed. I began to suspect that it was a problem with the algorithm school itself!"
"After some calculations, I found that the Tolkien faction made mistakes in handling data disturbances. It was not inaccurate or error-prone. It was a real mistake! Only the Youdeyi faction can come up with the real answer!"
Song He was about to continue talking when he was interrupted.
"The Tolkien school has errors?" Xiong Maoxun didn't believe it at all and questioned bluntly, "The Tolkien school is a classic school that has been widely used in various countries in the past ten years. How could there be an error? Even if there is an error, how could everyone not find it? "
"Just like this question." Song He reached out and poked at the test paper. "The answers are 87.667 and 87.687 respectively. Will such a small difference attract any attention? Even if there is a deviation between the calculated value and the measured value of the explosive test explosion, the analyst People will also think that it is environmental factors or instrument errors, and it is difficult to doubt the algorithm itself."
Xiong Maoxun was not convinced at all, shook his head and crossed his arms, "You want to prove that the Tolkien faction is wrong, can you specify it?"
Song He pulled out the blank paper from the side without saying anything, "I will calculate it on the spot, follow my ideas, and you will understand where the mistakes are."
He started writing eloquently, while explaining quickly.
The three heads next to him came over and scrutinized his derivation process without blinking.
"Under the action of the solidification driving force ΔGm, liquid phase atoms transform from high free energy G1 to low free energy G2 and must cross the energy barrier ΔGd..."
"What's the difference? Tolkienists simply and crudely regard the Gibbs free energy of the system as the following form. The change in body free energy plus the surface energy of the interface between the new phase and the old phase is equal to..."
"Normally, there is no problem with Tolkien's algorithm, but this question happens to involve low supersaturation and a large critical nucleus size. When there are only a few to dozens of atoms, it will produce The error is large because only body free energy and surface energy are considered, and other effects are ignored..."
"The Youdeyi Sect deals with this aspect very complicatedly, but this complexity is necessary and cannot be simplified. Why? The crystal buds can freely translate and rotate in the mother phase, which will inevitably reduce the formation energy of the crystal buds!"
Song He explains quickly.
The three people next to him were obviously struggling to follow.
Yu Anbang and Xiong Maoxun stopped from time to time, thinking with sweat on their heads, and occasionally raised a question, but Song He could always cut the problem with a single blow!
The students in the classroom looked eagerly at the podium. They were all shocked by this scene and started talking about it.
"Holy shit, Song He is giving a lecture to Teacher Yu?"
"What's going on? Is the question on the test paper controversial?"
"The controversial thing is that Teacher Yu taught the questions according to the reference answers. Why Song He? Does he want to challenge the reference answers?"
"Anyway, Song He definitely didn't do well in the exam. I'm afraid he will have to fight hard and struggle to the death."
The buzz from the students became louder and louder. Yu Anbang patted the microphone and said, "School is over! Students can go!"
The whole class picked up their schoolbags and left, looking back frequently before leaving. A few bold students ran to the podium to listen. They didn't understand at all, so they could only suppress their curiosity and leave.
The classroom was empty except for the four people on the podium.
Song He talked with a dry mouth until half past ten, and finally ended.
"It's very clear at this point. The correct answer to the first big question should be 87.687 which I did. This is the correct result obtained by the You Deyi Sect!"
"The 87.667 derived by the Tolkien School seems to have only a slight error, but in fact it is completely wrong! This question has special circumstances and cannot be solved using the Tolkien School's wrong ideas!"
After saying that, Song He put down his pen and looked at Yu Anbang.
Yu Anbang looked embarrassed, "You mean, you are the only one who got this question right, while Xiong Maoxun, Ye Li, and the reference answers were all wrong?"
"Exactly!" Song He nodded firmly, "Teacher, what do you think?"
"To be honest, I'm not sure." Yu Anbang was confused and looked at the large paper filled with the calculation process.
Xiong Maoxun and Ye Li next to him also looked confused. Although they interrupted and asked several questions along the way, they didn't understand.
Song He was helpless. The Youdeyi sect was indeed too advanced. It took him a long time to figure it out. It was indeed difficult to clarify his thoughts in a short time.
Yu Anbang took out his mobile phone and sent two messages, "Teacher You Deyi will be here soon. He should be able to judge right from wrong. Do you want to wait?"
"Wait!" the three students said in unison.
Whether this question is right or wrong is related to the final exam grade. If you are not sure, how can you sleep tonight when you go home?
After only waiting for two minutes, You Deyi appeared with a cigarette in his mouth, short and unruly hair, and an old formal suit. He seemed to have sneaked out of some meeting.
"Let me see, what question stumped my dear disciple?" You Deyi's eyes lit up.
"It's an old question, and there were no problems in previous exams. Song He suddenly said that the reference answer was wrong." Yu Anbang explained, "He thought that there were loopholes in the Tolkien school, so he used your school to solve it."
"My style?" You Deyi's eyes were suddenly brighter than a cigarette butt, and then he was dubious, "Is my style so easy to master? Don't just follow Dong Shi's example, right?"
After that, he lowered his head to read the question, glanced at the question, picked up the scratch paper that Song He had calculated, and squinted at it.
You Deyi puffed out smoke, blowing smoke from his nostrils, like a heat engine running at high speed until it was filled with smoke.
Except for Xiong Maoxun, the other three people hid aside to avoid inhaling too much second-hand smoke.
Five minutes later, You Deyi looked happy, put down the papyrus, and looked at Song He meaningfully.
